Modes for Carrying Out the Invention

[0015] The optimal embodiment of the present invention will be briefly described with reference to the drawings to show the operation of the present invention.

[0016] In the cylinder 1 of the piston mechanism, the air pumped and introduced by the pressure feeding air supply mechanism collides and burns with the fuel or is compressed and burned by the piston 2 of the piston mechanism andAn engine that uses that force as power to transmit (acquire) it, and has a pressure-fed air introduction part 3 as a pressure-fed air supply part that pressure-feeds and introduces the air to be pressure-fed into the cylinder 1. The pressure-fed air introduction part 3 has a number of introduction openings 4 as its air supply ports, and when the air is pressure-fed and introduced, the number of introduction openings 4 are in an open state where they all open simultaneously, combustion and is configured to be provided with an opening / closing switching mechanism 6 (an opening / closing type pressure-fed air supply mechanism) including an opening / closing part 5 that can be opened and closed as an air supply valve that is in a closed state where all are closed at times.

[0017] This opening / closing switching mechanism 6 is provided with a movable wall part 5 for opening and closing as the opening / closing part 5 between an outer wall part 7 where the number of introduction openings 4 are provided and an inner wall part 8 where the number of introduction openings 4 are provided at a position in communication with the number of introduction openings 4. The movable wall part 5 for opening and closing is provided so as to be movable (for example, rotatable), and a number of introduction openings 9 for opening and closing are provided at positions on the movable wall part 5 for opening and closing that are in communication with the number of introduction openings 4 on both sides of the communication state between the outer and inner sides.

[0018] For example, a disk-shaped or trumpet-shaped air supply valve (the opening / closing part 5 for opening and closing) provided with a number of slit-shaped air supply ports (the number of introduction openings 9 for opening and closing) is rotatable (the number of introduction openings 4 can be opened and closed) at a position sandwiched between an outer wall part 7 provided with a number of slit-shaped upper air supply ports (the number of introduction openings 4) and an inner wall part 8 provided with lower air supply ports (the number of introduction openings 4), and is provided with an opening / closing type pressure-fed air supply mechanism that is vertically movable (pressure-contact closing and release rotation possible).

[0019] When the movable wall part 5 for opening and closing, which is the air supply valve (opening / closing part), moves (for example, rotates between the outer wall part 7 and the inner wall part 8 as described above), the number of introduction openings 9 for opening and closing are displaced from the number of introduction openings 4 on the outer and inner sides and enter a closed state where the number of introduction openings 4 are all closed. And when the movable wall part 5 for opening and closing moves and moves in a direction approaching the outer wall part 7 or the inner wall part 8 (for example, rotates and moves in either the vertical direction), it is configured to enter a pressure-contact closing state where the movable wall part 5 for opening and closing is in pressure contact with the outer wall part 7 or the inner wall part 8.

[0020] When switching from this pressure contact closed state to the open state, by moving the movable wall portion 5 for opening and closing in the separating direction, the pressure contact state between the movable wall portion 5 for opening and closing and the outer wall portion 7 or the inner wall portion 8 is released, and by moving (for example, rotating) the movable wall portion 5 for opening and closing, the multiple introduction openings 9 for opening and closing communicate with the multiple introduction openings 4 in the communicating state therebetween to form an open state.

[0021] For example, in synchronization with the movement of the piston 2, forced supply of pressurized air causes it to collide and burn or compress and burn with fuel combustion At this time, by the instantaneous one-way operation that moves in one direction and approaches and separates in one direction, the introduction of pressurized air can be performed instantaneously, and combustion It can withstand the high combustion pressure at this time and reliably prevent the backflow of the combustion gas to the air supply side.

[0022] Specifically, for example, in synchronization with the movement of the piston 2, in order to introduce and supply the pressurized air into the cylinder 1 near the top dead center of the piston 2, the movable wall portion 5 that is in pressure contact with the inner wall portion 8 and blocks the pressurized air and receives the pressurized air pressure for opening / closing is received by the inner wall portion 8 in the pressure contact closed state, and the movable wall portion 5 for opening and closing moves in one direction and moves away from the inner wall portion 8 to form the open state, and the pressurized air is forcibly supplied and fuel is injected combustion to be configured like this.

[0023] And at this combustion time, the movable wall portion 5 for opening and closing further moves in this one direction as it is and approaches and moves to the outer wall portion 7 to form the pressure contact closed state in which it is in pressure contact with the outer wall portion 7, so that combustion at this combustion the movable wall portion 5 for opening and closing that receives the pressure is configured to be received by the outer wall portion 7.

[0024] That is, when introducing the pressurized air into the cylinder 1 (during pressurized air supply), the opening / closing movable wall portion 5 moves in one direction from the pressure contact blocking state and moves away from the inner wall portion 8 to enter the open state. By being released from the pressure contact state, the movement for this opening can be made smooth and easy. And by further moving in this direction, it can be instantaneously blocked again and the pressure contact blocking state can be achieved, thus enabling it to withstand the pressure during combustion. combustion It has a structure that can withstand the pressure.

[0025] Therefore, although it has a structure that can be pressure contact blocked, for example, even an actuator with a small driving force can be opened and closed and switched to the open state. Also, it can be designed with high power and the exhaust gas is clean.

[0026] Also, during air supply cutoff, the opening / closing movable wall portion 5 moves in the opposite direction, moves away from the outer wall portion 7, and approaches and moves toward the inner wall portion 8 to come into pressure contact with the inner wall portion 8, thus entering the pressure contact blocking state. It can withstand the air supply pressure (pressurized air pressure) and seal to prevent the pressurized air from leaking into the cylinder 1.

[0027] In this way, for example, by reciprocatingly moving (for example, reciprocatingly rotating) in synchronization with the piston 2 of the piston mechanism, the opening / closing introduction opening portion 9 is displaced between the introduction opening portions 4 in the communication state, and it can be switched between the simultaneous blocking state, the simultaneous opening state, and the simultaneous blocking state. And by this operation in the reverse direction, it can be switched between the simultaneous blocking state, the simultaneous opening state, and the simultaneous blocking state again.

[0028] Furthermore, in addition to this movement, since it moves in the approaching / separating direction, the intermediate opening / closing movable wall portion 5 comes into pressure contact with the outer wall portion 7 or the inner wall portion 8 when closed, and separates and the pressure contact is released when open. Therefore, it can be instantaneously switched between the simultaneous pressure contact blocking state, the simultaneous pressure contact release opening state, and the simultaneous pressure contact blocking state with a small force, and the introduction and cutoff of the air supply, as well as the cutoff and opening introduction by the pressure contact blocking state that can withstand the air supply pressure and combustion pressure, can be made smooth and reliably switched.

Example

[0029] Explanation will be given to Specific Example 1 of the present invention with reference to the drawings.

[0030] In this example, air and fuel that are pressure-fed and introduced by a pressure-feeding air supply mechanism are caused to collide and burn in cylinder 1 of a piston mechanism, and are also compressed and burned by this piston 2, so that combustion can occur without an ignition device, and the combustion force at this time is used as power and transmitted in an engine (internal combustion engine), which is an engine equipped with a pressure-feeding air supply mechanism for pressure-feeding air into cylinder 1 from a pressure-fed air forced introduction port (the air supply port of the present invention) different from a normal air supply valve (air intake port) 19, to which the present invention is applied.

[0031] Although various configurations can be adopted for this engine, in this example, a piston 2 that moves up and down is provided in cylinder 1. As the piston 2 reciprocates up and down, air is inhaled from air intake port 19, and at the same time, air is also pressure-fed, introduced, and supplied from the air supply port by the pressure-feeding air supply mechanism. This pressure-fed air and the fuel injected into cylinder 1 from fuel injection unit 21 collide and burn, and are compressed and burned by this piston 2, and the when force of the combustion is obtained as power via piston 2, and after combustion, the exhaust gas is exhausted from exhaust port 20. The present invention is applied to a gasoline engine.

[0032] This pressure-feeding air supply mechanism of this example is provided with an opening / closing switching mechanism 6 including a large number of introduction openings 4 in a pressure-fed air introduction part 3 (air supply port) for pressure-feeding and introducing the pressure-fed air into cylinder 1, and an opening / closing part 5 that can be opened and closed and that is in an open state in which all the introduction openings 4 are opened simultaneously during pressure-feeding introduction and in a closed state in which all are closed at other times. combustion It has a configuration in which an opening / closing switching mechanism 6 is provided.

[0033] This opening / closing switching mechanism 6 of this example a plurality of the is provided with a movable wall part 5 for opening and closing as the opening / closing part 5 movably between an outer wall part 7 where the introduction openings 4 are provided and an inner wall part 8 where the large number of introduction openings 4 are provided at a position in communication with the large number of introduction openings 4. The movable wall part 5 for opening and closing has both the communication states between the outer and inner sides a plurality of theA configuration is provided in which a large number of opening / closing introduction openings 9 are provided at positions in a communicating state with the recording introduction opening 4. By moving the opening / closing movable wall portion 5, a plurality of the the recording opening / closing introduction opening 9 a plurality of the is displaced from the recording introduction opening 4 to enter a closed state in which the large number of introduction openings 4 are blocked all at once. Moreover, as the opening / closing movable wall portion 5 moves and moves in a direction approaching the outer wall portion 7 or the inner wall portion 8, the opening / closing movable wall portion 5 comes into a pressure-contact closing state in which it is in pressure contact with the outer wall portion 7 or the inner wall portion 8. When switching from this pressure-contact closing state to an open state, by moving the opening / closing movable wall portion 5 in a separating direction, the pressure-contact state between the opening / closing movable wall portion 5 and the outer wall portion 7 or the inner wall portion 8 is released, and by moving the opening / closing movable wall portion 5, and a plurality of the openings the closing introduction opening 9 is configured to be in a communicating state and an open state with the large number of introduction openings 4 in the communicating state.

[0034] Specifically, the pressure-feeding air supply mechanism of this Example 1 is configured to provide a cylindrical surrounding portion 11 that covers the cylinder communication opening 10, which is the air supply port of the pressure-feeding air introduction portion 3, and to pressure-feed and introduce air by an air pressure-feeding portion 16 that employs, for example, a compressor or the like within this surrounding portion 11. A disk-shaped outer wall portion 7 is provided at the upper part within this cylindrical surrounding portion 11, and a disk-shaped inner wall portion 8 is provided at a vertical interval below this so as to block and communicate with the cylinder communication opening 10. Between this outer wall portion 7 and the inner wall portion 8, a disk-shaped opening / closing movable wall portion 5 as the opening / closing portion 5 is provided so as to be horizontally rotatable therebetween and to be reciprocally movable in a direction approaching and separating from the outer wall portion 7 and the inner wall portion 8.

[0035] The disk-shaped outer wall portion 7 is provided with a large number of slit-shaped introduction openings 4 having a length in the radial direction and spaced at intervals in the circumferential direction. The inner wall portion 8 below this is provided with a large number of slit-shaped introduction openings 4 so as to face this, and this is configured to be the cylinder a series of communication opening 10.

[0036] Also, between the upper outer wall portion 7 and the lower inner wall portion 8, an opening / closing movable wall portion 5 is provided so as to be rotatable and vertically movable. The opening / closing movable wall portion 5 has an air supply port in a vertically communicating state (both on the outer and inner sides), a plurality of the which is in communication with the introduction opening portion 4 and becomes the same slit-shaped a plurality of the opening / closing introduction opening portion 9 in the open state. By horizontally rotating, the multiple opening / closing introduction opening portions 9 are displaced, a plurality of the and a closing portion 12 is provided between the slits to block the introduction opening portion 4 all at once to enter the closed state.

[0037] Therefore, in this embodiment, as described above, in synchronization with the movement of the piston 2, the opening / closing movable wall portion 5 is horizontally rotated in one direction and approaches and moves to one side of the upper and lower outer wall portions 7 or the inner wall portion 8, so that from the pressure contact closing state in which it is in pressure contact with the other side, it becomes the open state, and then the pressure contact closing state in which it is in pressure contact with the one side. Also, when the opening / closing movable wall portion 5 is horizontally rotated in the opposite direction and approaches and moves to the other side of the outer wall portion 7 or the inner wall portion 8, it changes from the pressure contact closing state in which it is in pressure contact with the one side to the open state and then to the pressure contact closing state in which it is in pressure contact with the other side.

[0038] Specifically, in synchronization with the movement of the piston 2, in order to introduce and supply the pressurized air into the cylinder 1 near the top dead center of the piston 2, the movable wall portion 5 that is in pressure contact with the inner wall portion 8 and blocks the pressurized air and receives the pressurized air pressure for opening / closing is rotated in one direction from the pressure contact closing state received by the inner wall portion 8 and moves away from the inner wall portion 8 to become the open state, and the pressurized air is forcibly supplied and fuel is injected by combustion being configured in this way.

[0039] And in this embodiment, at the time of this explosion, the opening / closing movable wall portion 5 further rotates in the same one direction and approaches and moves to the outer wall portion 7 to enter the pressure contact closing state in which it is in pressure contact with the outer wall portion 7, so that combustion at this combustionThe movable wall portion 5 for opening and closing that receives pressure is configured to be received by this outer wall portion 7.

[0040] That is, when introducing the pressured air into the cylinder 1 (during pressured air supply), the movable wall portion 5 for opening and closing rotates in one direction from the pressure contact and closing state and moves away from the inner wall portion 8 to enter the open state. However, when released from the pressure contact state, the rotation for this opening can be made smooth and easily performed.

[0041] And by further rotating in this direction, it can be instantaneously closed again and brought into the pressure contact and closing state, so it is configured to withstand the pressure during combustion. combustion Therefore, although it is configured to be able to perform pressure contact and closing, for example, even an actuator with a small driving force can be opened and closed and switched to the open state. Also, it can be designed with high output, and the exhaust gas is clean.

[0042] Also, when the air supply is cut off, the movable wall portion 5 for opening and closing rotates in the opposite direction, moves away from the outer wall portion 7, and approaches and moves toward the inner wall portion 8 to enter the pressure contact and closing state where it is in pressure contact with the inner wall portion 8, and is configured to be able to withstand the air supply pressure (pressured air pressure) and seal the leakage of the pressured air into the cylinder 1.

[0043] To explain further, in this embodiment, near the top dead center where the piston 2 of the piston mechanism reaches the top dead center, in order to introduce and supply the pressured air into the cylinder 1, from the pressure contact and closing state where the movable wall portion 5 that is in pressure contact with the inner wall portion 8 and blocks the pressured air and receives this pressured air pressure is received by this inner wall portion 8, the movable wall portion 5 for opening and closing rotates in one direction and moves away from this inner wall portion 8 to enter the open state, and the pressured air is forced to be supplied and fuel is injected. combustion It is configured in this way.

[0044] That is, from the pressure contact and blocking state in which the movable wall portion 5 that receives the pressure-fed air pressure and is in pressure contact with and blocking the inner wall portion 8 is received by the inner wall portion 8, the opening / closing movable wall portion 5 is rotated in one direction and moves away from the inner wall portion 8, so that the opening state is achieved and the pressure-fed air is forcibly supplied, and fuel is injected combustion configured to do so.

[0045] And at this combustion time, the opening / closing movable wall portion 5 further rotates in this one direction as it is and moves closer to the outer wall portion 7, and when it comes into pressure contact with the outer wall portion 7 to enter the pressure contact and blocking state, combustion at this combustion the opening / closing movable wall portion 5 that receives the pressure is configured to be received by the outer wall portion 7.

[0046] That is, when introducing the pressure-fed air into the cylinder 1 (during pressure-fed air supply), from the pressure contact and blocking state, the opening / closing movable wall portion 5 is rotated in one direction and moves away from the inner wall portion 8, so that the opening state is achieved. Since it is released from the pressure contact state, the rotation for this opening can be made smooth and easily performed. And by further moving it in this direction, it can be instantaneously closed again and the pressure contact and blocking state can be achieved, so that it can withstand the explosion pressure during combustion.

[0047] In this way, near the top dead center of the piston 2, the introduction of the pressure-fed air and the combustion are occur instantaneously. After that, near the bottom dead center where the piston 2 descends again, from the pressure contact and blocking state in which the opening / closing movable wall portion 5 is in pressure contact with the upper outer wall portion 7 and withstands the combustion pressure during combustion near the top dead center, the opening / closing movable wall portion 5 is rotated in the opposite direction by a drive mechanism capable of reciprocating movement and moves away downward, that is, by moving away from the pressure contact and rotating, the state in which a large number of introduction openings 4 serving as air supply ports are simultaneously opened is achieved, and further the pressure contact and blocking state in which it is in pressure contact with the inner wall portion 8 is achieved.

[0048] Then, when the piston 2 rises again, the combustion gas is exhausted from the exhaust port 20. At this top dead center, the exhaust port 20 closes and the introduction opening 4 (the air supply port for the pressured air) remains closed. Separately from this, an intake port 19 provided separately like a normal engine opens, and as the piston 2 descends, air is introduced for intake. By introducing this new air, the inside of the cylinder 1 after combustion is cooled, and by rising again, it is compressed and the output is improved.

[0049] Then, from this bottom dead center, the piston 2 rises again, and near the top dead center, the introduction and combustion of the pressured air are are configured to be carried out.

[0050] Also, the pressured air supply mechanism of this embodiment includes an opening / closing drive part 13 (rotation actuator) that horizontally rotates the opening / closing movable wall part 5 of the opening / closing switching mechanism 6 provided in the pressured air introduction part 3 between the outer wall part 7 and the inner wall part 8, and a pressing / separating drive part 14 (vertical movement actuator) that moves the opening / closing movable wall part 5 closer to and away from the outer wall part 7 and the inner wall part 8. However, the opening / closing drive part 13 (rotation actuator) of this embodiment is configured such that a central rotation shaft of the opening / closing movable wall part 5 projects upward and a rotation arm part for reciprocally rotating this central rotation shaft is provided, and a drive part (rotation actuator) that reciprocally swings this rotation arm part back and forth is provided.
